A. Lange & Sohne - Richard Lange Jumping Seconds in Pink Gold

First introduced in 2016, the Richard Lange Jumping Seconds combined a jumping second, a constant-force escapement, and a ZERO- RESET mechanism with a regulator dial layout.
After the inaugural platinum model, A. Lange & Söhne is presenting a second version in pink gold, also in a limited 100-watch edition. The 39.9 mm x 10.6 mm case frames a solid silver, argenté dials with a prominent blued-steel seconds hand and smaller pink gold hours and minutes hands.

The Richard Lange Jumping Seconds pays tribute to watches for scientific observation and puts the focus on the smallest of the three time measurement units.

In 60 steps per minute, the blued seconds hand advances along the upper and largest circle of the regulator dial. The cadence is defined by an ingenious one- second constant-force escapement that serves two purposes. On the one hand, it delivers the switching impulse for the seconds jump, and, on the other, it assures constant power delivery for the entire power reserve of 42 hours. A small indication in the intersection of the three time circles tells the owner when to rewind the watch: it switches to red ten hours in advance.

The function of the constant-force escapement can be observed close up through the sapphire-crystal caseback. The aperture reveals how the remontoir spring of the constant-force escapement receives fresh energy from the mainspring barrel every second to power the escapement at the same rate.

Just below it, under a transparent jewel bearing, there is a star connected to the fourth-wheel arbor that controls the jumping seconds sequence.

The ZERO-RESET mechanism is also easily visible. When the crown is pulled, it stops the cam-poised balance and instantly propels the seconds hand to the zero position. This allows the watch to be conveniently and precisely synchronised with a time signal or a radio-controlled clock.

An innovative multi-disc clutch reliably stabilises the large seconds hand throughout the accelerating and braking phases to assure perfect one- second legibility of the time.

Beating at 21,600 vibrations per hour, the hand-wound manufacture calibre L094.1 guarantees a power reserve of 42 hours. The finishing of the 390-part movement meets the highest standards with bridges made of untreated German silver and decorated with Glashütte ribbing, hand-engraved balance cock, eight screwed gold chatons.
